Hi Buddy,
Check the KBase article :
http://kbase.redhat.com/faq/FAQ_40_5338.shtm
Short cut :
chkconfig rlogin on
chkconfig rexec on
chkconfig rsh on
then service xinetd restart
I have verified all these services work on RHEL4, with SElinux in
'enforcing' and the iptables firewall stopped. rcp on a Linux system
does not prompt for a password, so you need to have a /etc/hosts.equiv
on the RHEL4 system that defines the hosts and users allowed to rcp..
You can trouble shoot the network side by running tcpdump on the rsh-server:
tcpdump -i eth0 host remote-host
Note that when you rsh to a RHEL system running rsh-server, it attempts
a high port connection back to the client, so check out what you AIX
system expects.
Cheers
